Nilgai

Systematic position. The Nilgai (Boselaphus tragocamelus) belongs to the family Bovidae and the order Artiodactyla. As the largest antelope in Asia, it is considered a major agricultural nuisance in regions where wild populations interact with human-cultivated farmlands, leading to significant economic losses for farmers.

Crops damaged. Nilgai are known for their preference for highly nutritious agricultural forage. They frequently target fields of wheat, millet, mustard, pulses, and sugarcane. Additionally, they are known to feed on the tender shoots of orchard trees, causing long-term structural damage to fruit-bearing plantations.

Biology and life cycle. These antelopes exhibit a high degree of adaptability to varied environments. They breed throughout the year, with peak calving periods often coinciding with optimal vegetation growth. Their social structure and mobility allow them to roam across extensive territories, often exploiting farmlands located near forest edges or scrublands.

Character of damage and harmfulness. The primary form of damage is the consumption of young seedlings and mature plants, which directly reduces grain yield. Beyond grazing, the physical impact of a large group of antelopes moving through a field leads to trampling, soil compaction, and the destruction of irrigation equipment, effectively ruining the harvest.

• Installation of robust perimeter fencing or solar-powered electric wires.
• Deployment of motion-activated floodlights or sirens to deter animals.
• Use of chemical repellents based on predator scents or bitter tastes.
• Strategic planting of unpalatable border crops to discourage entry.
• Implementation of community-based wildlife management and monitoring programs.
